This study conceptualizes, operationalises and validates the concept of Knowledge Management Competence as a four-phase multidimensional formative index. Employing survey data from 310 respondents representing 27 organizations using the SAP Enterprise System Financial module, the
study results demonstrate a large, significant, positive relationship between Knowledge Management
Competence and Enterprise Systems Success (ES-success, as conceived by Gable et al., 2008);
suggesting important implications for practice. Strong evidence of the validity of Knowledge Management Competence as conceived and operationalised, too suggests potential from future research evaluating its relationships with possible antecedents and consequences.
